We know Star Wars Rebels is headed into it's 4th and final season, so what's next? And when? The more I think about it the less I want it to take place post episode VI, Filoni could have a golden opportunity to "bridge" the PT to the OT and also the ST!
I'm about 90% certain Thrawn will survive season 4 of SWR, so we need some explanation of where he was during the OT. And what if these characters we've grown to love don't die at the end of season 4?
What if the next series focuses on events between IV - V and then between V- VI! We can really expand the galaxy and bind it together! We haven't seen Boba since TCW, Cad Bane etc.
I know we have 30 years between VI and VII but I don't think we'll be digging into that timeline until after IX.
Thoughts?

I adore the way they took care of Thrawn in this show and kept the decency that made his character an EU top pick (i.e. his social workmanship contemplate as a window into the psyches of his adversaries). I had a few issues with the show at an early stage, yet it truly has developed and the character improvement is really consistent with Star Wars.

I’m hoping for a post-OT series to bridge the gap between that and the ST. The only thing I’d be concerned about is between the Empire disappearing and the rise of the First Order, it doesn’t appear there was a great deal going on on the galactic stage. From Blood Lines onwards that changes. But I guess you could really dive into the underworld following the Galactic Civil War, which would be quite cool.

Damn Filoni is wrapping up SWR so amazingly! Congrats on binding the three trilogies together! With only 3 episodes left in the series A Fools Hope", "Family Reunion" and "Farewell" I hope we get a trailer for the next animated series at the conclusion of Farewell!

At the conclusion of SWR Sabine gives a recap of the characters post RotJ, it's safe to say the next animated series will be filling in some of the events in the 30 year gap between VI and VII. And Thrawn will be in it!https://www.youtube.com/watch?v=chIheNEHpbA

It will take place prior to events in TFA. Characters known to feature are Poe Dameron, Captain Phasma and BB8. Oscar Isaac and Gwendoline Christie will voice their characters.

Dave Filoni said the idea came out of his interest in WW2 aircraft and pilots. I think it also comes out of the popularity of the X-Wing book series. Instead of Rogue Squadron, it will be Black Squadron.

Star Wars Insider reports that Christopher Sean will voice Kazuda Xiono who is Resistance pilot recruited to spy on the First Order. Chris currently appears in Days of Our Lives for those wanting to check out his voice.
